| (54) | CONCEPT FOR COMBINING CODED DATA PACKETS WITH ROBUST HEADER PROTECTION |
| (57) Concept for transmitting payload data (112-m) from a transmitter (110-m) to a receiver
(120) via a communication channel within a time interval (T), wherein a plurality
of channel-coded data packets (210-n) are generated from the payload data (112-m)
within the time interval (T), wherein each of the channel-coded data packets comprises
packet core data (212-n) corresponding to a packet identification of the respective
channel-coded data packet, and wherein the packet core data is coded with a channel
code of higher redundancy than the payload data (112-m). The plurality of channel-coded
data packets (210-n) are sent, within the time interval (T), without any return channel
to the receiver (120), which comprises a decoder (DEC) adapted to decode packet core
data (212-1) of a first received channel-coded data packet (210-1) of the time interval
(T), and, if error-free decoding of the first channel-coded data packet (210-1) so
as to obtain the payload data (112-m) fails, to decode packet core data (212-2) of
at least one second received channel-coded data packet (210-2) of the time interval
(T) so as to determine a suitable further channel-coded data packet of the time interval
for combination with the first channel-coded data packet so as to obtain, on account
of the combination, an increased code gain for decoding of the payload data.
